Abstract
A first interface board includes a first signal processing unit that performs a predetermined process on a signal. A second interface board includes a second signal processing unit that performs the predetermined process on a signal. When no failure occurs in both interface boards, a switching control unit selects the first interface board. When a failure occurs in the first interface board, the switching control unit selects the second interface board. When there is no failure in both the interface boards and the first interface board does not satisfy a predetermined degradation condition, the electrical power supply control unit supplies electrical power to the first interface board and prohibits the supply of electrical power to the second interface board. When there is no failure in both the interface boards but the predetermined degradation condition is satisfied, the electrical power supply control unit supplies electrical power to both the interface boards.
